How do you use Portals to stay warm during exploration?

Staying warm in Valheim''s cold biomes, such as the Mountain biome, is crucial for survival. Cold weather inflicts the Freezing debuff, which reduces health regeneration and stamina recovery, making exploration and combat more challenging. One effective strategy to combat this is using Portals to create temporary safe havens for warmth and recovery.\n\nPortals are a late-game crafting item that allows players to teleport between two linked points. To craft a Portal, you need 20 Fine Wood, 10 Greydwarf Eyes, and 2 Surtling Cores. Fine Wood is obtained from Birch or Oak trees, Greydwarf Eyes drop from Greydwarfs, and Surtling Cores are found in Burial Chambers or dropped by Surtlings in the Ashlands biome. Once crafted, place two Portals and name them the same to link them.\n\nTo use Portals for warmth, set up a base in a safe biome, such as the Meadows or Black Forest, with a Campfire or other heat source. Build a Portal at this base and name it something memorable, like ''WarmBase.'' Then, carry the materials for a second Portal with you when exploring cold biomes. When you start to feel the effects of the Freezing debuff, quickly place the second Portal, name it the same as your base Portal, and step through to warm up.\n\nThis strategy is particularly useful in the Mountain biome, where the Freezing debuff is constant unless you have Frost Resistance Mead or Wolf Armor. For example, if you''re mining Silver or fighting Drakes, you can place a Portal near your mining spot or combat area. When your health or stamina gets low, teleport back to your warm base, recover, and return fully refreshed.\n\nOne common challenge is running out of materials to build Portals. To avoid this, always carry extra Fine Wood, Greydwarf Eyes, and Surtling Cores in your inventory. Additionally, consider setting up multiple Portals in different cold areas to minimize travel time. For instance, you could have one Portal near a Silver vein and another near a Frost Cave.\n\nAnother tip is to combine Portals with other warmth strategies. For example, bring Frost Resistance Mead or wear Wolf Armor to extend your time in the cold. This way, you can explore longer before needing to teleport back. Additionally, always keep a Campfire or other heat source at your base to ensure you warm up quickly.\n\nIn summary, Portals are a versatile tool for staying warm in cold biomes. By setting up a warm base and carrying Portal materials, you can create a quick escape route to recover from the Freezing debuff. This method is especially useful in the Mountain biome, where the cold is relentless. With proper planning and resource management, Portals can make cold biome exploration much safer and more efficient.\n\nPractical tips: Always carry extra Portal materials, set up multiple Portals in key locations, and combine Portals with other warmth strategies like Frost Resistance Mead or Wolf Armor. This approach ensures you can explore cold biomes with confidence and minimal risk.
